Abstract:A closed-cell metamaterial absorber (CCMA) made of a low-permittivity dielectric is proposed and investigated in this paper. It realizes five absorption peaks below −10 dB in the range of 6–18 GHz, and the strongest absorption can reach near −40 dB. By investigating the distribution of electromagnetic fields, it is found that multi-resonance is caused by the embedding of closed cells. Interestingly, it is possible that part of the absorption peaks could be moved individually by different parameters of the closed-cell arrays. Similarities between the results of experiment and simulation confirm the practical feasibility of the CCMA.
